80445 LG Dryer - Instructions

I assumed this was a belt problem. Ordered the belt and followed the excellent screw by screw instructional YouTube provided by PartSelect. In fact, I probably would not have attempted the repair, until I watched the video and was reassured that I could do it. When I got the front panel off, the problem was obvious. There was a dishrag stuck in the blower. Didn't need the belt, but the video was sure worth the price of the part (~$17). Mr. Appliance charges $109 to DIAGNOSE the problem! This was way easier than dealing with them, especially during a pandemic near the holidays.

Followed the instruction on video.was great after three parts now is OK .we have heat.still cheaper than having it service.

Called LG on the phone and they gave the button presses for diagnostics, which then gave the HST code, saying the Humidity sensor was bad.
The part was described as the Humidity sensor module. Actually it's just the wire leads for the sensor which must be electronic and only accessible by disassembling the dryer. There were descriptions about cleaning the wires, perhaps because some people use dryer sheets which cause a buildup on the wires and prevent them from doing their job. I use wool balls and have no buildup on my wires and replacing them did not fix the sensor, because the module accessible inside the dryer is not the moisture sensor, but only the wire leads.

With a thin flat screwdriver I was able to pry out the old door switch, I replaced it with the new door switch, pushed back in dryer and so far is working since I installed a month ago.

Unscrew the screw, remove old part, place in new part, replace screw and you are done.

This was all pretty straightforward with the helpful video hosted on this site. The only issues I ran into was I had a seized screw that stripped and I had to drill it out and replace it. Also, I had to disassemble the front and rear a little bit further than what is shown in order to install the new roller axles. I was pleasantly surprised that I did not have to worry about the triangular retainers, because the replacement rollers/axles use an improved metal retaining pin. Overall, I'm very happy and the dryer is nearly silent now. It was a bit of a challenge but I took my time and gave myself breaks throughout the morning rather than banging my head against the wall.

There’s all sorts of videos on it I watched. It was actually very simple

watched the video on line then did the repair, very easy to replace

Removed the top, the control panel and the door. The heater assembly came out thru the front, without having to remove the drum. Easy replacement

An appliance repairman determined the problem which was that it needed new pulleys and thankfully PartSelect carried them. He installed them in an hour and my dryer runs fine now.

Viewed YouTube video form parts select to take dryer apart. Very easy to do if you just follow instructions in the video. Nothing too hard to do. Of note the 4 pack roller assembly is a whole unit, so you’ll have to replace the stem unit the old rollers use and not just replace the roller wheels like in the video. That is a different part number from LG. The front 2 are pretty straight forward to unbolt and replace. The back 2, especially one on the left is tighter clearance even with a wrench. If you’re able to pull whole dryer out and take back off, it’s an easier to get the one on the back left.
Also replaced belt just because i had it open, I replaced thermistor previously after getting a Te5 code about a year ago so that helped in taking it apart.
Would recommended doing it all since you’ll have it open.
Once replaced, everything ran again.

Pull filter out and replaced with new one.

Removed cover replaced bulb

Slide out old filter then slide in the new one.

After trying duct tape to fix the tear, I decided to see if I could just order a new one. Part Select was the first company I found listed, so I ordered one. It was not expensive and it was delivered very quickly! It works so well s as me I’m a very happy customer!
